Even i am planning to go for same model , Can you please let me know what should be water tank height to have solar system to get right pressure for flow .. it seems i got it wrong where our contact tor installed the tank at 2 feet platform height .. planning for alternate like get new stand dedicated for solar ..

1) You should keep the Water Tank should be at least 6-8 feet above the Solar Heater Tank2) Ensure the Solar panel should be placed in such a way the Panel should face South West direction as more sunlight will be there.
